To all whom/ it may concern:

Be it known that I, ARTHUR MARTIN ROE- MER, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented. certain new and useful Improvements in Heating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to improvements in heatingapparatus or systems for: brooders, incubators, and other structures,

and has for its object the production of an apparatus in which especial provision is made for heatingand circulating induced currents of hot air in sucha manner as to secure perfeet ventilation and the discharge of foul air and odors.

The main purpose ofthe invention is to pro-. vide an apparatus combining simplicity of construction with maximum efficiency and durability in use and which will maintain a down upon the interior of the brooder. Fig. i 2 is a longitudinal section of the same on line;

2 2 of Fig. 1. 3 3 of Fig. 1.

Fig. 3 is a section on the line Fig. 4 is a section on line 4 4 of Fig. 1.. Fig. 5 is a View looking toward out, however, intending to limit the invention thereto or to the details of construction In the presentinstance I have shown theap i. plicationpfthe invention to a-brooder with-I which for the purpose of illustration I have setforth.

It will of course be understood that the invention is equally as well adapted for use in incubators, houses, and structures of all drawings, the numeral 1 represents the in- 5 closing walls of the brood er or structure which is tobe heated and which is illustrated. as being dividedby longitudinal partitions 2 2 and transverse partitions 3 3 into a heating-chamber 4 and rooms or compartments 5 and 6,

which are to be heated by hot air supplied from said heating-chamber. The inclosing walls maybe of any construction shown in structures of this character.

The heating-chamber 4 is subdivided by a .horizontal metallic wall or partition 7 to provide a lower compartment to receive the heating device and an upper compartment 9 for containing the radiating devices which heat 1 the air priorto its introduction into the rooms or apartments 5 and 6 of the brooder or struc- ;ture. Ifidesired, also,the hot-air compartment 9 may be directly closed at top byga metallic wall or ceiling 10 and at its ends by similar vertical walls 11, so as toincrease the surface forthestorage of heat from the heating device in order that there maybe a more thor- .ough and effective transmission of heat by radiation to'the entering currents of air.

The heating device 12, arranged in the basecompartment 8 of the heating-chamber, consistsin the present instance of an ordinary drum are banks of heat-radiating pipe 16 and 16. These pipes extend transversely of the compartment 9 and are mounted at their ends in headers 17, each of which consists of a pair of suitably-spaced metallic sheets united by bolts or rivets. The headers supporting the outer ends of the pipes serve as supports for auxiliary heating-drums 18 and 18, disposed, respectively, in longitudinal alinement with the two sets of chambers or apartments 5 and 6 on opposite sides of the longitudinal partitions 2 and 2. From these drums 18 extend fines or conductors 19, which project through the partitions 3 and 3' along the upper portions of the apartments 5 and 6 and connect at the opposite end of the brooder or structure from the heating-chamber 1 with vertical outlet-fines 20, leading to the atmosphere through the top of the-brooder orstructure. The said flues 19 open into the vertical flues 20 near the upper ends of the latter, and said fines 20 project down to near the bottom of the apartments 5 and 6 and are open at their lower ends for the discharge of the foul air and odors from said apartments in the manner hereinafter described. The compartments 5 and 6 are in communication through doorways or openings 21, which when the invention is embodied in a brooder may be closed by flexible curtains or flaps 22, which are adapted to readily open to allow the heated air to pass from the apartments 5 to the apartments 6 and also to allow the chicks to pass from one compartment to the other, said ourtains being constructed of a material which will yield easily under pressure for these purposes.

The main drum 15 containsa V-shaped divider or deflector 23, which is located centrally above the opening connecting said dru in with the flue 13 and is adapted to deflect the products of combustion flowing. from the heater in opposite directions and equally to both sets of radiating-pipes 16 and 16'. From the drum the products of combustion and hot air passing upward through the fine 13 are thus caused to circulate in equal ratio or proportions to said pipes 16 and 16 and to flow therethrough to the auxiliary drums 18 and 1S, and thence to pass from said drums into the lines 19 and through the latter along the entire length of the brooder or structure in the upper portions of the compartments 5 and 6, and finally to pass out to the atmosphere through the vertical outlet-fines 20. The discharge of the products of combustion into the top of these fines 20 causes the production of a partial vacuum in said fines, whereby the foul air contained within the chambers 5 and 6 is caused to pass up into the flues by the suction or draft thus induced and then to discharge to the atmosphere, by means of which the automatic continuous circulation of air through the compartments 5 and 6 is established and a constant discharge of the foul or vitiated air produced.

Pure air to be heated is supplied to the interior of the compartment 9 through fresh-air ducts or fines 23, leading from the exterior through the opposite side walls of the brooder or structure beneath the bottom of said compartment-namely, beneath the partition 7- to the center of the heating-chamber and openinginto said chamber at a pointin line with the partition 2 and adjacent to the partition 3. The fresh air supplied through these fines or ducts passes into the front portion of the comparttheir upper and inner ends arranged in line with passages 25, formed in the transverse partition 3. By this means the air, which is preliminarily heated to a certain temperature by indirect radiation from the metallic walls of the heating chamber and drums, is caused to circulate about and around the heatingpipes 16 and 16, and thus to become heated to a higher temperature before passing into the chambers 5. All of the available heat from'the products of combustion from the heater is thereby utilized during the flow of said products through the apparatus to heat the air both by direct and indirect radiation. The course of the products of combustion through the brooder or structure has been previously described, and it will be seen that the heated air flowing through the passage 25 into the apartments 5 and 6 will be caused to flow rapidly through said compartments by the suction or draft created by the discharging products in the lines 20, so that all liability of sudden changes of temperature within the brooder will be effectually avoided. hen the structure is employed as a brooder, the downward course of the air in passing from the inlets 25 to the doorways 20 will cause the same to pass immediately over the backs of the chicks contained in the apartments 5, thus keeping them warm and dry.

In order to establish a more thorough circulation and temporary retardation of the air within the hot-air chamber 9, I preferably mount the pipes 16 and 16 in vertical rows, with the pipes of one row located in line with spaces between the pipes of adjacent rows, thus giving them a staggered relation, whereby the air is caused to circulate about to a greater extent in order to find an outlet through said pipes, and this becomes heated to a higher degree before entry into the chainbers 5.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be readily understood, and it will be seen that a simple and efiective form thereof.

Having thus described the invention, what is claimed as new is 1. In combination, a series ofcompartments in communication at their lower ends through a flap-controlled doorway, a heating-chamber having communication at its upper end with the compartment nearest thereto, 'an outlet at the farthest end of the remote compartment in communication with the lower end thereof, a heater in the heating-chamber comprising a drum, a pipe extended through the series of compartments and in communication with the said drum at one end and with the aforesaid outlet at its opposite end, and means for supplying fresh air to the heatingchamber, substantially as described.
